| Phagocytosis refers to the process by which certain living cells called phagocytes engulf other cells, particles and even pathogens. |
The Phagocytosis process occurs when the cell tries to destroy foreign particles or pathogens such as bacteria or an infected cell by engulfing them and lyse them with lytic enzymes. This process is also observed in single-celled organisms such as amoeba during the ingestion of food particles.
In humans, phagocytic cells protect the body by ingesting harmful pathogens like viruses, bacteria, and other infected/ dying cells. In fact, phagocytosis is a vital aspect of the immune system and is undertaken by special cells like neutrophils and macrophages. By destroying the pathogens, the immune system stops the spread of infection or pathogens in the body.
